To all whom it may concern: 1

Be it known that we, ETIENNE Rama and Ann: PILLON, citizens of the French Re public, of Oullins, Rhone, France, have invented certain new and useful Improvements in Valves, of which the following is a specification.

The invention relates to combinations of valves forcOntrolling and regulating the flow of liquid, as for example in connection with the service pipe of a domestic water supply system whereby water is supplied to a cistern and thence through branch pipes to various household taps.

In regard to certain elements of the combination, the valve resembles the valve described in the specification of our co-pending application for Letters Patent filed 7th June 1918, Ser. No. 238715. v V

The inventionis illustrated'in theaccompanying drawings, in which Figure 1 is an end view in elevatlon.

Fig.2 a section on the line 41-2; of Fig. 1,

Fig. 3 a section on the line B-B of Fig. 2.

Figs. 4 and 5 are sections similar to Fig. 2, but showing the valve plugs in different positions and omitting the actuating part or the device.

The device comprises a massive body 12 cast in one piece comprising two chambers 12 and 12 the former with an inlet port A1, and the latter with a delivery port S. In the central part of the casting 12 there is another chamber 18, communicating with the chambers 12 and 12 by means o1 ports 16 and 17 respectively. The chamber 18 is divided into two parts by means of a screw plug 19 having a passagetherethrough, an exchangeable diaphragm within this plug having a hole of a size in accordance with the terms or conditions under which the To the chambers 12 and 12 are screwed two large caps 14 and 15 respectively, and with these caps the said chambers form housings for two plugs 4 and 4 slidable therein. The cap 15 has a discharge portt. Between the cap 14 and the chamber 12 the plug 4 which is rotatable as well as slidable is surrounded by a fixed collar 5 whose edge on one side is shaped in two curves 5 and 5 to form a ramp for an abutment 3 fixed to the plug. The pressureot the water in i the plug holds the abutment firmly against the ramp, and rotation of the plug Specification'of Letters Patent.

produces an axial displacement thereof, with three normal positions of rest, to wit, at the flattened ends and central part of the-ramp. The plug 4 is open to the interior of the cap 14. The end of the plug 4 within the cap 15 is closed.

@utside the chamber 12 the plug 4 'carries a disk 20 having a handle 24 and three notches 24 Upon the disk 20 are marked three index letters D, F and 'O, 90 degrees apart. Outside the chamber 12 the plug 4 carries a slotted head 21 with which the rim of the disk 20 is engaged, so that the plug 4 is coupled with the plug 4 for axial movement. Theslot in'the head 21 allows the disk 20 to rotate.

- Within the head 21 there is a coiledspring 22 thrusting a small ball 23 against the rim o1 the disk 20, so that when. anyone of the notches 24 reaches this ball, in the course of the rotation ot the disk 20,.the ball enters points i to the notch andlightly restrains the'disk. A

'The plug 4 has two circular series Off. orifices, 10 and 10 ,v and carrlesran abutfr'nent 8 itis embracedby two flanged and perforated rings"? and 7, with washers-or packing rings 9 the'holes 8 inthe ring 7 being located below the inlet port Ar, to

give access to the orifices 10 in certain positions of the plug, as shown in Flgs. 2 and 4. In the position shown in Fig. 5, the holes: The

10 are withdrawn from the ring 7 orifices 10 are placed so that in one position of the plug theyare'within the ring 7 as shown in Fig. 2 and allow water to fiow from the plug through the holes 8 in that ring to the port 16 and chamber 18. In the positions shown in Figs. 4 and 5 the orifices 10 are withdrawn from thering 7 The plug 4 has three circular series of orifices 10 10 and 10 and is surrounded by two flanged and perforated rings 7 and 7 with packing rings 9 In one position of the plug shown in Fig. 2, the orifices 1O 18, duct 1, and holes 8 in the ring 7 and water flows out of the plug through the orifices 10 and the holes 8* in the ring 7 to the port S. In another position of the plug 4 shownin Fig. 4, the orifices 10 are removed from the ring 7 and the-orifices 10- trom the ring 7 in this position the orifices 10 are within the ring 7 In the third position of the plug, shown in Figf), the orifices 10 are still covered, and the orifices 10 still within the ring 7 but the orifices 10 are open to the interior oi": the cap 15.

,From the foregoing description of the construction the action of the valve will be clear. With the parts in the position shown in Fig. 2, obtained by setting the disk so that the pointer points to the letter O, water can flow from the inlet port Arthrough the plug l chamber 18, and plug 4L to the delivery port S. By setting the disk with the pointer at F the position shown in Fig. i is obtained, in which the plug l cuts oil the flow of water from the port A to the chamber 18 and plug 4 With the dislrset at D, and the parts in the position shown in 5, the flow or" water is still cut off by the plug 4 but the plug 4 allows water to ilow back from the cistern or the like through the port S the holes 10 to the cap 15, and thence through the discharge port 5. p

What we claim as our invention and desire to secure by Letters Patent of the "United States is 4 1. In a valve the combination of a housing having an inlet port and an outlet port, a

hollow cylindrical plug slidable and rotat-' able in said housing and having orifices spaced apart in the axial direction of the plug, two periorated rings surroundmg said plug, each having two flanges seated against the plug and the housing and each ring straddling one of said ports with its flanges, washers surrounding said plug adjacent said IifIgS, means for axially moving said plug,

including a ramp in the housing and an abutment on the plug coacting with said ramp, whereby the plug orifices are moved into and out of said rings, a second housing having an inlet port and two other ports, a second hollow cylindrical plug, axially movable in said second housing and having three orifices spaced apart in the axial direction 01"" said plug, two perforated rings surrounding said second plug eachhaving a pair of flanges seated against the plug and the housing, said pairs 0; flanges straddling the inlet port .and one of said other ports respectively, waahers surrounding the'second plug adjacent said rings, a chamber connecting the outlet port of the first housing to the inlet port of the second housing, and means coupling the second plug with the firstmentioned plug for axial movement whereby said second plug alternatively opens communication between the inlet port of the second housing and one of the other ports of said housing, or between the last-mentioned port and the third Port of said housing.

2. lhe combination claimed in claim 1, the means coupling the two plugs including a slotted head fixed to the second plug and a disk fixed to the first plug, engaging said slotted head.

In witness whereof we have signed this specification in the presence of two wit nesses.
